Combined Elastic and Limit Analysis for Seismic Vulnerability Assessment of Pitched Portal Frames

Buildings
This paper presents a combined approach for the seismic vulnerability assessment of pitched portal frames by coupling elastic and limit analysis. Pitched portal frames are widely adopted both in civil and industrial building structures, as well as in ...

Do Marine Protected Areas Reduce Poverty? A Systematic Review and Critical Evidence Synthesis of Socioeconomic Outcomes in Southeast Asian Coastal Communities

Sustainable Development, EarlyView.
ABSTRACT Marine Protected Areas (MPAs) are widely recognised as a key strategy for conserving marine biodiversity while advancing sustainable development. Beyond ecological conservation, MPAs are increasingly expected to improve livelihoods and reduce poverty among coastal communities that depend on marine resources.

Stresses in Above‐Ground Storage Tanks Subjected to Flood‐Borne Debris Impact

Safety Science and Technology, EarlyView.
This study investigates the stresses induced in above‐ground storage tanks by flood‐borne debris, specifically steel pipes and wood poles. Findings demonstrate that debris impacts across the examined velocity range generate stresses within safe limits, not exceeding the yield stress threshold.

Study on Regular Inspection Frequency of Bridge Based on Seismic Vulnerability Analysis

Shock and Vibration, 2018
This study introduces a method to obtain accurate results regarding bridge seismic cost and reduce structural seismic losses. A three-span reinforced concrete (RC) continuous bridges model consistent with the reality was established, and seismic ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

TRM‐to‐concrete interface bond without anchors: Combined experimental, analytical, and numerical modeling approach

Structural Concrete, EarlyView.
Abstract Textile reinforced mortar (TRM) systems have emerged as an effective alternative to conventional FRP strengthening solutions due to their compatibility with concrete substrates and favorable performance under adverse environmental conditions.

Post‐earthquake field assessment and damage correlation of elevated reinforced concrete water tanks in Kahramanmaras/Elbistan, Türkiye

Structural Concrete, EarlyView.
Abstract This study evaluates the seismic performance of elevated reinforced concrete (RC) water tanks in the Elbistan region following the February 6, 2023 Kahramanmaras–Elbistan earthquakes. Field investigations, visual damage surveys, non‐destructive testing (ultrasonic pulse velocity—UPV), concrete compressive strength measurements, peak ground ...

Information technology and management of diagnostics for analysis of seismic vulnerability in buildings

Procedia Computer Science, 2011
AbstractEnsuring the safety of a building in the event of an earthquake requires analysis of its vulnerability. The analysis is undertaken to evaluate the damage expected in the building for a possible earthquake of pre-established energy. To achieve this, a calculation model has to be prepared, referred to structural and typological characteristics in

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

Structural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.
